FOLDED BOX. AND PROCESS OF MAKING THE SAME.

Application filed March 3, 1921.

T 0 all whom it may concern:

Be it known that I, ELIE W. LABOMBARDE, a citizen of the United States,andresident of Nashua, in the county of Hillsboro and State of NewHampshire, have invented a new and useful Folded Box and Process ofMaking the Same, of which the following is a specification.

One object of my invention is to provide a simple and inexpensive boxbut at the same time a durable one and another object is to construct abox having outside flaps in such a way that the flaps will be protectedagainst any tendency to separate them from the walls with which theycooperate.

A feature of my invention is the provision of a wall formed to besubstantially flush with the ends of the flaps and in the preferred formthe wall has a depression or recess for this purpose.

Another feature is an offset formation to permit the flaps to swingneatly along the adjacent wall. I

Another feature is the structure by which one wall forms an abutment foranother wall.

Other features will be pointed out below.

In the drawing:

Figure 1 is a perspective view of abox embodying my invention;

Figure 2 is a plan of the blank on a smaller scale Figure 3 is a partialplan of said blank partially folded;

Figure 4C is a partial plan of the folded box;

Figure 5 is an edge view of the device of Figure 4;

Figure 6 isapartial section on line 66 of Figure 1;

Figure 7 is a partial plan of a modification- Figure 8 is a partialsection similar to that of Figure 6;

Figure 9 \is a partial edge view of one wall of the box, the flap beingomitted;

Figure 10 is an elevation of the reenforcing strip; and

Figure 11 is an end elevation thereof.

My box is preferably made from a blank of cardboard or similar materialhaving a base A; a wall formed of portion A foldable at the scoring aand portion A foldable at the scoring a; a similar wall having portionsA and A; another wall having a portion A foldable at a this portionhaving Serial No. 449,452.

flaps A and A each being pointed as I shown, said other wall comprisingalso portions A foldable at a and another wall comprising similarportions A and A and flaps A and A Port-ion A is cut through at 7) toreceive the pointed end of flap A and at b to receive the end of flap Aportion A being similarly out through at Z1 to receive the end of flap Aand at 6 to receive the end of flap r Reenforoing strips are preferablyused and each is connected by glue or otherwise with one flap and withthe adjacent portion of its wall, each strip being preferably flat andmade of very thin paper bent double at b b and enclosing a cord Z) oftextile material, the ends projecting in Figure 10 but being cut offwhen the desired length of the strip as a whole is out 01f.

In Figures 7, 8 and 9 I show a modification in which the base D has sidewalls 0? and cl each of a single thickness the end wall being double asindicated at d d provided with flaps 01* and d The wall at is indentedor pressed in in triangular form as indicated at cl to receive flap dwhich has a pointed end as described in connection with the other form,said end being glued within said indentation so that it is substantiallyflush with the other surface of the box. The wall 03 might be pressedoutwardly and thus furnish protection for the pointed end and such formis within the broad contemplation of my invention. A similar indentationd is formed in wall d to receive flap d In making the form of Figures 1to 6 the reenforcing strips are preferably applied and then portion Abent over on portion A and glued thereto and then both portions aremoved into vertical position and similarly for portions A and A PortionA is folded over on portion A and glued to the latter and to thereenforcing strips, these portions being folded into vertical positionand the flap A at its pointed end being bent into opening 5 and glued tothe then outer surface of portion A said end being at its outer surfacesubstantially flush with the then outer surface of portion A so thatsaid end is protected. Flap A enters similarly into opening 7). PortionsA and A are similarly folded and flap A fastened in opening Z) and flapA fastened in opening 6 In the form of Figures 7 to 9 the walls, d, cl,d and (Z are folded into vertical position and flap d enters indentationd and is glued there and similarly with (Z in indentation (Z It will beobserved that portions A and A are off-set from the scoring a so thatwhen portion A is folded over inwardly it may act as an'abutment for theadjacent edges of portions A A A and A the olfset being suflicient toprovide room for portion A and also by permitting portions A and A to bebent in slightly from the vertical I am able to swing flap A clear ofportions A A at the bend of the flap which is highly important inpreserving the strength of the flap. Similar offsets are provided at theother corners.

It will be clear that the one advantage of my structure is that the endsof the flap are protected sothat if the box is pushed into a receptacleor cover the ends of the flaps will not become loosened or separatedfrom the walls of the box.

One advantage of the pointed ends of the flaps is that the :box willride easily into a receptacle with a minimum of resistance.

The use of reenforcing members is particularly important in connectionwith my flaps extending outside of the box because of the additionalstrain on the junction of the flaps with their respective walls.

What I claim is:

1. A box comprising a wall provided with a flap; and another wall havinga portion substantially flush with the end of said flap, the latterbeing connected to said other wall adjacent to said portion.

2. A box comprising a wall provided with a flap; and another wall havinga depression; said flap extending along outside of said other wall,entering said depression and being connected to said other wall.

3. A box comprising a wall provided with a flap; and another wall ofdouble ply, the outer ply having an opening through it; said flapextending along outside of said other wall, extending through saidopening and being connected to the inner ply of said other wall.

4. A box comprising a wall provided with a flap; a reenforcing stripconnected to said wall and flap; and another wall having a portion whoseoutside is substantially flush with the end of said flap, the latterbeing connected to said other wall adjacent to said portion.

A box comprising a wall provided with a flap; a reenforcing striconnected to said wall and flap at the inside thereof and consisting ofa flat member made of pa )er and a textile member enclosed by said papermember; and another wall having a portion whose outside is substantiallyflush with the end of said flap, the hitter extending at the outside ofsaid other wall and being connected thereto adjacent to said portion.

6. A box comprising a Wall having a flap with a pointed end; and anotherwall having a depression adapted to correspond with said pointed end;said flap extending along outside of said other wall, entering saiddepreslsion and being connected to said other wal ELIE W. LABOMBARDE.
